Cowboys sign Thomas, release Hoyte

Thomas, a former Texas Tech standout, led the Miami Dolphins in tackles in 10 of his 12 seasons. A seven-time Pro Bowl choice, he missed 11 games last season with a concussion.

The club also announced it has released fullback Oliver Hoyte. Hoyte joined the team in 2006 as an undrafted free agent out of North Carolina State and played in 24 games the past two seasons. He converted from linebacker to fullback in the middle of his rookie season.
